Yes, hrrmmm... my fault, I did
printf("value = %d", value); instead of
printf("value = %d", (int)value);
Oooops.
Anyway, I am trying to build a virtual serial driver. Does anybody
know how to do this with gcc (what compiler/linker flags, and options
to build-prc), or what settings I need with Code Warrior? If anybody
has done this, or know where it is documented, help would be greatly
appreciated.
